It’s terrible practice, I know, but my password is the name of my dog. My dog’s name is H^7a(;tQ.

UPDATE: I’m being notified by various systems that my dog’s name doesn’t meet the minimum name length, so I have renamed my dog to Y05!z[2@,*HUps%3. If it weren’t for the number and special character requirements, I had planned to just name him the Diceware passphrase ‘doublespadeambiguouslactationconsultant’.
